Custom B2B Software Development

Custom CRM, ERP and SaaS software for complex B2B operations.

I design and build Laravel-based systems that automate quoting, orders, inventory, approvals, subscriptions and integrations—without forcing your team into generic software.

Workflow before features

Requirements follow real records, decisions and exceptions.

Laravel delivery

Server-rendered applications with maintainable domain logic.

Reliable integrations

Validation, retries, idempotency and visible reconciliation.

Ownership and handover

Project source code, deployment notes and practical documentation.

Services

Software services for connected B2B operations

Each engagement starts with the operational constraint. The service category describes the main system boundary; related CRM, ERP, SaaS and integration work can be delivered together when the workflow requires it.

Custom CRM

Accounts, opportunities, requirements, quotations and approvals designed for complex B2B sales.

Custom ERP

Order, procurement, inventory and production workflows with clear controls and traceability.

Operational outcomes

What the software should make easier to control

The outcome is defined against the current workflow. No generic percentage or deadline is promised before the relevant data and constraints are understood.

One dependable record

Reduce conflicting customer, product, order or stock information across teams.

Fewer manual handoffs

Validate and carry structured data forward instead of retyping it between tools.

Visible exceptions

Show failed integrations, overdue approvals and operational discrepancies to the people who can act.

Traceable decisions

Preserve who approved, changed or corrected a commercially important record and why.

Delivery process

Four steps from workflow to maintainable software

  1. 01

    Discover

    Map representative records, users, rules, exceptions, data ownership and existing systems.

  2. 02

    Define

    Agree the first complete workflow, acceptance criteria, dependencies and exclusions.

  3. 03

    Build and review

    Release in small slices, test critical rules and review with the people who use the process.

  4. 04

    Launch and hand over

    Rehearse migration, deploy, verify operations and document the system for its next owner.

Technical delivery

A foundation your team can inspect and operate

Technology choices are documented against the workflow and operating environment. Laravel is the usual application foundation; third-party platforms remain where they are the better source of truth.

Security boundaries
Role and record-level permissions, validation and protection of sensitive actions.
Critical-path tests
Automated coverage for tenant isolation, approvals, financial rules and integrations.
Operational visibility
Logs, failed-job context and reconciliation paths for background work and APIs.
Repeatable delivery
Environment configuration, migrations, deployment notes, backups and handover guidance.

FAQ

Questions before a custom software project

When does custom software make more sense than an off-the-shelf product?

Custom development is usually justified when a workflow is commercially important, spans several systems or depends on rules that generic software cannot support without repeated workarounds. Discovery should still compare configuration and integration options before a build is recommended.

Can you integrate with our existing CRM, ERP or accounting platform?

Yes. The first step is to define which system owns each record and how failed or delayed updates will be reconciled. Existing systems can remain authoritative while a custom application connects the workflow around them.

How do you scope a first release?

A representative workflow is mapped from start to finish, including users, approvals, exceptions, data ownership and integrations. The first release is the smallest complete path that creates an operationally useful result.

What happens after launch?

Handover includes source code, deployment and operational documentation appropriate to the project. Ongoing maintenance can be agreed separately, or the system can be transferred to an internal or third-party development team.
